Proper Use of Hydraulic Hammers/Breakers
The first step in breaker preventative maintenance is to use the tool properly. “Operator skill remains the foremost determiner of breaker service life,” says Tom Munch, business development representative, Caterpillar. Here are seven things to keep in mind.

Match the breaker to the carrier. The carrier (typically an excavator) must be of the right weight class and have the right hydraulic pressure and flow. Too small a carrier or too little hydraulic power will reduce breaker performance. Too much of either will create excessive heat and wear in the breaker. Also match the breaker to the application.
Always have the tool tip perpendicular (90 degrees) to the material being broken.

History of the excavator hydraulic hammer
Hydraulic breakers are the oldest hydraulic attachments for carriers. The first serial manufactured rock breaker was the Krupp HM 400 in 1967 and the patent was secured in 1963. Excavator jack hammers are impact devices designed to break any kind of rock or concrete with any hardness or physical property. They have a wide range of applications such as demolition, deconstruction, primary rock excavation, secondary rock breaking, trenching, foundation work, asphalt cutting and many others.

Today our excavator hydraulic hammers are available from ~ 50 kg to more than 10,000 kg of operating weight for any kind of carrier. Over sixty years of development of the breaker hammers has produced advances at different levels, such as self-lubricating systems, sound & vibration damped systems, automatic rock hardness adjusting systems, energy recovery, solid body concept and much more.
